IPrintOemDriverUni COM Interface

The IPrintOemDriverUni COM interface provides a rendering plug-in with access to utility operations supplied by the printer graphics DLL for Unidrv. These operations send a data stream to the print spooler, and obtain driver-managed information.

The following table lists and describes all of the methods defined by the IPrintOemDriverUni interface.
